Paras Sethia discovered that libcurl would sometimes mix up multiple
HTTP and HTTPS connections with NTLM authentication to the same server,
sending requests for one user over the connection authenticated as
a different user (CVE-2014-0015).

libcurl can in some circumstances re-use the wrong connection when
asked to do transfers using other protocols than HTTP and FTP, causing
a transfer that was initiated by an application to wrongfully re-use
an existing connection to the same server that was authenticated
using different credentials (CVE-2014-0138).

libcurl incorrectly validates wildcard SSL certificates containing
literal IP addresses, so under certain conditions, it would allow
and use a wildcard match specified in the CN field, allowing a
malicious server to participate in a MITM attack or just fool users
into believing that it is a legitimate site (CVE-2014-0139).
